Wastewater treatment of electroplating industries is essential due to high pollution and contamination of soil and water. It seems to be that due to high water consumption of these industries, it is essential to reuse and recycle the treated wastewater. In this research, removal of aluminum and sulfate from the wastewater using Nanofiltration pilot in anodizing aluminum industry was studied. The influential parameters for process are wastewater concentration, temperature and pressure which studied through pilot studies. NF-90 used as Nanofiltration module which is prepared and manufactured by Filmtec Company. The temperature and pressure intervals were 30, 35, 40°C and 5, 7.5, 10, 12.5, 15, 20 bar, respectively. The results demonstrated that the best aluminum and sulfate removal obtain at 7.5 to 12.5 bar pressure and temperature of 30°C. The pressure and temperature increments induced to flux increment.
